Ocean salt water entering Delaware River due to drought and sea level rise, water managers say

7. I assume the reservoirs serve some function.

So drawing them down just to provide flow might wind up getting in the way of what is obviously a lesser group of people being served. Either numerically or in terms of importance.

Do what I've head others have done: move the intake ports upriver, either by canal or pipeline. I mean, LA has huge underground water channels that they built to bring in water from the mountains.

The Schuylkill intake point may not be safe, either. Depends on the elevation of the intake and water flow rates. Brackish water can move up the Schuylkill just as well as it can move up the Delaware, provided that the pressure and elevation work out just wrong.
